Product Description

Megger MOM2 BD-59092 240 A Micro-Ohmmeter for High-Current Contact Testing

The Megger MOM2 BD-59092 is a lightweight, battery-powered micro-ohmmeter delivering up to 240 A DC for low-resistance measurement of switchgear and breaker contacts. It uses ultra-capacitor technology to deliver high current bursts without requiring mains power, and is compatible with the DualGround™ method for safe testing while both sides remain grounded.



Why It Helps

  • Measures from 1 µΩ to 1000 mΩ with automatic range selection for switchgear and bus-bar applications.
  • Delivers up to 240 A peak test current (actual output depends on load and lead length).
  • DualGround™ permits testing with both sides grounded for enhanced operator safety.
  • Bluetooth® connectivity for data transfer and optional audio headset feedback.
  • Battery-operated portable design (≈ 2.2 lb instrument).


Key Highlights

  • Output current: up to 240 A DC (capacitor discharge) | Voltage max 2.5 V.
  • Resolution 1 µΩ – 1 mΩ | Accuracy ± 1 % of reading ± digit (0–1999 µΩ).
  • Selectable test duration 0.1 s, 0.6 s, or 3 s with automatic discharge.
  • 190-result data memory with timestamp and pass/fail tag.
  • Rechargeable NiMH pack (5 × AA cells) and AC adapter included.


Applications

  • Contact resistance testing of low-, medium-, and high-voltage circuit breakers
  • Verification of bus-bar and disconnect switch connections
  • Ground bond integrity and protective conductor testing
  • Field maintenance for substation and industrial equipment
